This book constitutes the thoroughly refereed joint post-conference proceedings of the 6th International Symposium on High-Performance Computing, ISHPC 2005, held in Nara, Japan, in September 2005 and the First International Workshop on Advanced Low Power Systems 2006, ALPS2006, organized as satellite event of the 20th ACM International Conference on Supercomputing, ICS 2006, held in Cairns, Australia, in July 2006.
The ISHPC 2005 symposium contributed 15 revised full papers and 13 revised short papers as well as 6 papers from the Second High Performance Fortran (HPF) International Workshop: Experiences and Progress, HiWEP 2005, and 8 papers from the Workshop on Applications for PetaFLOPS Computing, APC 2005 - all of which were carefully reviewed and selected from a total of 76 submissions. The volume is completed with 5 papers of the First International Workshop on Advanced Low Power Systems, ALPS2006, selected from 15 initial submissions that also passed a second round of reviewing and improvement. The papers are organized in topical sections on architecture of high performance computing, HPC applications or visualization, current HPF research, and low-power processing techniques in HPC.
